I purchased my 04 Crossfire brand new and it only had the airfoil on the passenger side. As for any of the German rubber products on my Crossfire, I have been less than impressed.
My gas cap "teather" dry rotted years ago, and my wiper blades split last year, without even being used a total of 6 hours in the last 4 years.
My car is always garaged, and never see's winter weather either.
